"Insert Balloon" Tool: Bentley Substation

I am trying to implement the use of the Balloon tool in my office and have some questions. 

1.  From the Device ID box there is a field for Balloon Number.  Right now that is a manual field.  Can this be directed to a field in the project datrabase so it is autofilled? We have standard item numbers already established and would like to use those in replace of the sequential format.

2.  We are adding accessory kits to all of our equipment.  When I add a balloon to the part it forces me to add 4 balloons to include the accessory kits.  Can I set it to only display the main balloon?

3.  Can I change the look of the balloon?  For example can I make it a hexagon versus the circle?

Thank you in advance.
